CUSHION VEHICLE TIRE.

Application filed February ,14, 1925. Serial NO. 9,221.

To (zi/Z w71 om t may concern:

Be it known that I, JOSEPH FINDLING, a subject of Aust-ria, residing vat New York city, county and Statel of New York, have invented certain Vnew and useful improvements in Cushion Vehicle Tires, of which the following is a specification.

'lhis invention relates generally to vehicle tires, and particularly to cushion tires adapted especially for use in connectionv i requires no attention after once being applied to a wheel.

A. still further object is to provide a tire of the character stated featured by the lack of complicated parts or mechanism, which is composed of but few simple and readily asscmbled parts, all so constructed and arranged as to minimized the opportunity for wear, breakage or derangement, which may be manufactured and supplied to the market at low cost, and which will prove highly effective in practice.

lith these objects in View, together with others which will appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts, all as will be disclosed more fully hereinafter, illustrated in the accompanyingl drawings and particularly pointed out in the claims.

In the drawing:

Fig. l. is a side elevation, parts broken away, of a tire core embodying the invention.

Fig. 2 is a transverse sectional view taken on the line 2 2 of Fig. l; and

Fig. 3 is a side elevation ofthe foundation removed from the tire core.

Referring now more particularly to the drawing, 8 represents a foundation formed of relatively hard rubber orother similar resilient or semi-resilient material. This foundation is circular in cross section and of annular formation, corresponding in diameter vto the central axis of the tire shoe with which it is vto be associated. This foundation is provided with a spiral groove 9 co-extensive with the foundation and a strand 10 of flexible resilient material is wound upon the foundation 8 in the groove 9 thereof. The strand l0 is of circular cross section and corresponds to the diameter of groove 9. The material of which the strand l is formed may be rubber, somewhat softer or more pliable than the material of which the foundation per Se is formed. Then the 'strand l0 is wound upon the foundation in the manner disclosed by Fig. 3, it will be observed that portions thereof project outwardly beyond t-he outer circumference of the foundation 8, and several wrappings of the strandV are disposed at varying angles. The meeting ends of these strands maybe cut away and overlapped and then secured together as by cementing, vulcanizing or in any other approved manner.

After the foundation has been wrapped with the strand and the ends of the latter have been Secured, the resultant core is placed within a mold and maintained therein. spaced even distances from the walls of the mold. The latter is then filled with plastic rubber, so that the latter entirely envelops the wrapped foundation and gains access to all grooves and recesses, thus firmly securing the foundation and the Strand lO together, and firmly. embodying the wrapped foundation in the fillet 12 of the surrounding rubber. The mold will be of a shape and Size corresponding with the shape and' size of the shoe with which the cushion tire is to be used.

The mold will salso be provided with suitable recesses at proper intervals, causing lugs 14V to be formed in the inner periphery of the Vfillet for engagement in recesses in a wheel rim. These lugs will seat within rim recesses so as to hold the fillet properly assembled upon the rim and against both latteral yand vcircumferential movements there-` on. The lugs 14 may be reinforced by more rigid elements projecting into the fillet and firmly anchored therein.

The tire cord thus constructed vis enclosed by a shoe and the latter may have proper tread reinforcement if desired, and may be beaded-to adapt itseli to a deinonntab'le rim. lith the tire core thus constructedv and assembled upon the rim, danger of detachmentot the same is eliminated, as the lugs l/liiiill be lirmly seated in proper recesses in the outer surface of the rim.

lilith a tire core thus constructed, it is apparent that a high degree et resiliency is obtained, due to the special construction. and` .i high degrceot' resiliency and yet of suiiti.

cient strength and toughness to withstand the severe strains and wear ytoirhichI it must necessarily ,be` subjected.

Having thns described my invention, l claim:

1. A tire ller having a spiral passage eX- tending longitudinally of said liller and a strand of more pliable material Within said passage.

2 fr tire [iller composed of resilient material and having a spiral circular passage extending longitudinally thereof and a strand of more pliable material, Within said passage.

In testimony whereof" I affix my signature.

JOSEPH FINDLNG.
